Impella 5.5®
Overview
Impella 5.5 with SmartAssist delivers full cardiac support with maximum unloading, allowing the heart to rest and recover.
It is a microaxial, surgically implanted heart pump that unloads the left ventricle, reduces ventricular work, and provides the circulatory support necessary to allow recovery and early assessment of residual myocardial function. It is designed for long-duration support and enables ambulation to optimize recovery while using real-time SmartAssist intelligence.
Clinical Evidence
A study published in the journal ASAIO examined the outcomes of the first 55 patients treated with Impella 5.5 with SmartAssist at Cleveland Clinic, Hackensack University Medical Center/Hackensack Meridian Health and Cedars-Sinai Medical Center. Study authors and cardiac surgeons Ed Soltesz, MD, Mark Anderson, MD, and Danny Ramzy, MD, conclude Impella 5.5 with SmartAssist is clinically appropriate for a number of challenging scenarios, including AMI cardiogenic shock.1

Part number: 0042-0010-US
The controller provides an interface for monitoring and controlling the function of all Impella catheters.
• 10.4” color display for easy viewing
• Mounts to controller cart (not shown) for transport within hospital
• 60 minutes of battery backup power for mobile transport
Axillary Insertion Kit
Part number: 0052-3009
Vascular access kit used for axillary insertion sheath of the Impella catheter.
• 2 graft locks

Purge Cassette
Part number: 0043-0002
5 Package: 0043-0003
The purge cassette delivers rinsing fluid to the Impella catheter. The purge fluid flows from the purge cassette through the catheter to the microaxial blood pump to prevent blood from entering the motor.

The Impella 2.5®, Impella CP®, Impella CP® with SmartAssist®, Impella 5.0®, Impella 5.5® with SmartAssist® and Impella LD® Catheters, in conjunction with the Automated Impella Controller™ (collectively, "Impella® System Therapy"), are temporary ventricular support devices intended for short term use (≤ 4 days for the Impella 2.5, Impella CP, and the Impella CP with SmartAssist, and ≤ 14 days for the Impella 5.0, Impella 5.5 with SmartAssist and Impella LD) and indicated for the treatment of ongoing cardiogenic shock that occurs immediately (< 48 hours) following acute myocardial infarction or open heart surgery or in the setting of cardiomyopathy, including peripartum cardiomyopathy, or myocarditis as a result of isolated left ventricular failure that is not responsive to optimal medical management and conventional treatment measures (including volume loading and use of pressors and inotropes, with or without IABP). The intent of Impella System Therapy is to reduce ventricular work and to provide the circulatory support necessary to allow heart recovery and early assessment of residual myocardial function.
The Impella 2.5, Impella CP, Impella CP with SmartAssist, Impella 5.0, Impella 5.5 with SmartAssist and Impella LD are contraindicated for use with patients experiencing any of the following conditions: Mural thrombus in the left ventricle; Presence of a mechanical aortic valve or heart constrictive device; Aortic valve stenosis/calcification (equivalent to an orifice area of 0.6cm2 or less); Moderate to severe aortic insufficiency (echocardiographic assessment graded as ≥ +2); Severe peripheral arterial disease precluding placement of the Impella System; Significant right heart failure*; Combined cardiorespiratory failure*; Presence of an Atrial or Ventricular Septal Defect (including post-infarct VSD)*; Left ventricular rupture*; Cardiac tamponade*
* This condition is a contraindication for the cardiogenic shock indication only.
Acute renal dysfunction, Aortic valve injury, Bleeding, Cardiogenic shock, Cerebral vascular accident/Stroke, Death, Hemolysis, Limb ischemia, Myocardial infarction, Renal failure, Thrombocytopenia and Vascular injury
In addition to the risks above, there are other WARNINGS and PRECAUTIONS associated with Impella devices.
